you will need either a new belt or idler pulley, different injectors, and a new computer tune.

oh, and maybe different spark plugs but thats iffy


i have also been told that at 2.8 pulley and lower you should do cooling mods but i havent got around to that yet myself.

 

im most likely going to get the 2.9 inch one. all im really looking for is whether or not i can just replace the pulley i have now and use the same belt and if it will bolt right up where the last pulley was

 

do you have a stage 2 now? if not you wont be able to run a 2.9 without blowing up your car. if you have a stage 2 your belt should be fine, if you dont then you will need a different belt or a different idler pulley. and the link you showed was for a hub and pulley so no it wont just bolt up. you will need a pulley puller to get the old one off, then you will use the pulley puller to press on the new hub, then you will be able to bolt on the pulley that you decided on.

 

yes i have S2. so if i buy this i will need the pulley puller right?

 

GM S2 needed to run anything smaller than 3.25. S2 is good to 2.8-2.9. Depends on altitude

No puller needed if yo have S2. Unless its not the same bolt pattern onthe pulley?

 

that part i dont know, i went from stock to what i have with out getting stage 2

 

alright so if i get this i should just be able to to bolt it right on then.. sorry for all the questions i just dont want to buy it and later find out i need to pay another 100$ on other **** lol

 

since you have stage 2 get this pulley and it will bolt right up http://cgi.ebay.com/ebaymotors/Chevy...mZ300134850929 Made by the same guy but this will bolt to the stage 2 hub

 

Like redline24 said, go with that and it will bolt right up to your stage 2 pulley system with no modification what so ever. Nate's pulleys are superb and you will be very happy with it. I do recommend paying the $5 extra dollars for the polished pulley and a set of his new bolts that are I think and extra $3. The reason I say go with the new bolts is that the stage 2 bolts are really weak and will strip eventually and you might need to save them for when you take the car back to the dealer for warranty work. So when you take you car back to the dealer you just put your stock stage 2 pulley and bolts back on and they will never know you have been messing with it and your stage 2 bolt will look fresh and new. Thats just my recommendation.

 

thanks guys

 

Damn, he didnt have the new bolts when I got mine. And yeah the blue paint is all going away on then :-S Plus I almost lost one the other day, man I was some worried

 

Nates 2.9 pully will fit on the gm stage 2 hub as long as you get the pully to fit the gm hub he has 2 different ones and you can run the 2.9 on the gm stage 2 tune

 

hahaha just look for blue bolts. that was easy enough. Blue bolts on ure supercharger means buy the 4 bolt 2.9 pulley from nate
